Success Story: A Postdoctoral Researcher From Spain Secures An NIW Success In Over 3 Months Without RFE
Client’s Testimonial:
"Chen Immigration Group was detail-oriented and did an excellent job preparing and writing my case in a way that minimized the possibility of RFEs. I have seen people with stronger profiles than mine receive RFEs, and I believe that often happens because of weak case preparation. From the beginning, their refund or refile policy gave me peace of mind and made me feel confident about moving forward with my petition. Their professionalism, attention to detail, and thorough approach made a real difference throughout the process."
On April 24th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Molecular Biology (Approval Notice).
General Field: Molecular Biology
Position at the Time of Case Filing: Postdoctoral Researcher
Country of Origin: Spain
State of Residence at the Time of Filing: Texas
Approval Notice Date: April 24th, 2026
Processing Time: 3 months, 24 days (Premium Processing Upgrade Requested)
Case Summary:
A molecular biology researcher with a Ph.D. in molecular biology and biomedicine secured approval of the I-140 NIW petition through a strong presentation of research focused on ERK1 and ERK2 signaling, cancer biology, and therapeutic response.
Key Credentials Presented in the Petition
- Ph.D. in molecular biology and biomedicine
- 5 peer-reviewed journal articles, including 4 first-authored articles
- 2 abstracts, including 1 first-authored abstract
- 1 first-authored preprint
- 106 citations to the client’s published work
- At least 11 completed peer reviews
- Research funding support from major national and institutional funding sources
Evidence of Significance
The petition did not rely on publication and citation numbers alone. Instead, it explained how the client’s 106 citations showed independent reliance on her work by other researchers studying kinase signaling, cancer progression, therapeutic resistance, and related molecular mechanisms.
The petition also highlighted citation percentile evidence, showing that several of the client’s papers ranked among highly cited articles for their publication years. This helped present the citation record as evidence of meaningful field influence. The client’s peer review activity further supported the argument that journals trusted her expertise to evaluate important research in molecular biology and cancer biology.
Expert Endorsements
The petition included 2 letters of recommendation from experts familiar with the client’s work. These letters supported the argument that the client’s research had already influenced molecular biology and cancer research and that she was well-positioned to continue advancing her proposed endeavor.
NIW Approval and Outlook
The I-140 NIW approval recognized the strength of the client’s molecular biology background, first-authored research record, independent citation impact, peer review service, funded research, and future research plans. We congratulate the client on this important approval and wish the client continued success in advancing molecular insights that may support improved cancer diagnostics, more precise treatments, and better patient outcomes in the United States.
